Supply trait still bugged?

[Yogol]

Hi,

 

Is there any official confirmation that the supply trait for cannons is still bugged?

Because... I just tested this myself, with 2 units of 24 6pdr fields.

They were placed next to each other and both had a colonel as boss.

One had the Logistics trait and one did not.

But... they both ran out of supply at the same time. So... is this a confirmed bug?
